Definition

A line is a perfectly straight path that goes on forever in both directions, with no beginning or end.

A zigzag line in a drawing can look full of energy, like a bolt of lightning.

How to teach this in 30 seconds

Try this analogy: A line in art is like the path your crayon takes for a walk across the paper — it can go straight, curl, zigzag, or loop.

Ask your child: What kind of line would a sleepy snake make?

Common mix-up: Kids might think a line always has to be straight. In art, a line can be straight, curvy, wavy, or zigzag, and different lines can show different feelings, like calm or excited.

Examples

  • A smooth, wavy line can look calm, like gently moving water.
  • A thick, dark line can feel strong, while a thin, light line can feel soft and delicate.

line is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
